BURNER-BLOCK AS APPLICABLE TO FURNACES.

Specification of Letters Patent.

ra'fiented March 26, 1907.

Application filed September 20,1906. Serial No. 335,372.

To (til whom it may concern:

Be it known that we, ISAAC H. BACON and Nine NELSON, citizens of theUnited States, residing at the city of Salem, in the county of Salem andState of New Jersey, have invented certain new and useful Improvementsin Burner-Blocks as Applicable to Furnaces, of which the following is aspecification.

Our invention relates to an improvement in burner-blocks as applicableto furnaces where oil is used as a fuel; and the object is to provide ablock so constructed that a more or less perfect combustion is obtained,thereby producing a greater degree of heat in proportion to theconsumption of fuel as compared with devices of this character now inuse.

With the foregoing object in view our invention consists in certainnovel features of construction and combination of parts, which will behereinafter pointed out, and de scribed in the claims.

In the accompanying drawings, Figure 1 is an end view of theburner-block. Fig. 2 is a top plan view. Fig. 3 is a vertical end view,and Fig. 4 is a vertical sectional view.

A represents the burner-block. The block is made of any suitablematerial, but preferably of cast-iron.

1 is an opening through which the heat passes into the furnace. (Notshown.)

2 is an opening located directly opposite the burner 3.

4 is the combustion-chamber.

5 is an air-flue passing, preferably, through the side of the chamber.

6 is a partition formed by the continuation of one side of the air-flue,as indicated by the dotted lines.

This partition is, however, not essential, but is made thus to avoid thesharp corners wherein the air could collect and to a certain extentproduce a back draft.

7 is a baffle-plate which is disposed between the restricted aperture 2and the airintake and inclined from the rear of the chamber toward theside of the air-intake, extending, preferably, to a point beyond themouth thereof.

8 is a pipe leading from the source of'the fuel supply (not shown) andhaving its burner end 3 in alinement with but preferably disposed insuch relation to the aperture 2 as to cause the fuel entering thechamber to entrain air with it. The bafiie-plate 7 is most desirablyformed as the bottom inclined wall of a laterally-inclosed bafile memberhaving side walls 8, which flareto the side walls of the chamber at anangle considerably greater than the inclination of the baflie-plateproper, 7.

B in Figs. 1 and 3 designates the front end of the block.

Our device is operative as follows: The block A is fitted under the capof a furnace, the fuelsupply which is under pressure is ignited at thepoint of burner 3, which drives the ignited fuel and air through theopening 2 into the combustion-chamber 4, meeting in thecombustion-chamber A the air which flows through the air-flue 5, wherethe combustion takes place, and the flame and heat is carried throughthe opening 1 into the furnace, (not shown,) to which the block isconnected. By the means of the partition 6 the air is directed into thecombustion-chamber. This partition may, however, be dispensed with, asthe same results may be had by the use of the baffle-plate 7, as theback draft caused by the sharp corners formed by the wall of the block Aand the bafiie-plate 7 are so trivial as to be of little or noconsequence as affecting the effectiveness of the device. Thebafiieaplate 7 is so arranged as to prevent the flow of oil or flamefrom the burner striking down into the air-flue beneath theburner-block, in that it extends within the block beyond a point wherethe flue enters. Also by being thus constructed the flow of air throughthe opening 5 does not meet the fuel from the burner 3 until said flowhas opened into a spray, which occurs a little distance from the mouthof the burner. The air flowing through the flue 5 and being directedbyithe partition 6 flows into the combustion-chamber 4, uniting with theoil after it has sprayed, and by this method of uniting a more perfectcombustion is produced.

Slight changes might be resorted to in the form and arrangement of theseveral parts herein described without departing from the spirit andscope of our invention. Hence We do not desire to limit ourselves to theexact construction as herein set forth; but,

Having fully describedljl our invention, what we claim as new,andidesire to secure by Letters Patent, is

1. In a burner-block, the combination of a chamber open at its front,means for delivering fuel and air through the rear of said chambertoward the front thereof, an alr-intake opening upward through the floorof the chamber, and a baffle-plate extending from the rear of thechamber beneath said delivery means downward and forward over saidairintake.

2. In a burner-block, the combination of a rectangular chamber open atits front end and provided with an aperture in its rear end and anair-intake through the rear of its floor, and otherwise imperforate, afuel-duct exterior to the chamben terminating adj acent but not fillingsaid aperture so as to deliver fuel and entrained air therethrough, anda bafHe-plate extending from the rear of the chamber beneath saidaperture downward and forward over said air-intake.

3. In a burner-block, the combination of a chamber open at its front endand provided with an aperture in its rear end and an air-intake throughthe rear of its floor, a fuel-duct exterior to the chamber terminatingadjacent but not filling said aperture so as to deliver fuel andentrained air therethrough, and a baffle member extending forward fromthe rear Wall of the chamber in alinement With said aperture and havingside Walls flaring laterally substantially to the side take openingupward through the floor of the chamber, a baflie-plate extending fromthe rear wall of the chamber beneath said delivery means downward andforward over said air-intake, and a second baffle-plate extending upwardand. forward from in rear of said iritake into proximity with said otherbaffleate.

p In testimony whereof We affix our signatures in presence of twowitnesses.
